Cummins is probably wrecked.
Starc definitely is like he is by the end of every summer where his stats plummet, and this time carried a niggle in, and at his worst Australian ground too. Hopefully he turns it around but it looks pretty stubborn. Not like we didn't have options.
They are a bit of a mess at the moment but usually with this sort of drama you'd expect the scoreline to be 4-0 going into the fifth test. But they are still in at and even at the MCG fought hard. I don't think India are just gonna roll over.
I'd do Webster and Jhye in, Marsh and Starc out.
Starc bowled brilliantly but they'd be crazy to play him with a niggle when he already drops off significantly by the 5th test of a series.
